To replace the battery in a Honda Fit car key, follow these steps: 1. First, open the remote key. 2. Find a coin or a flat-head screwdriver and insert it into the key slot as a tool to pry open the key cover. 3. With the side bearing the logo facing upwards, use the tool to gently pry upwards, applying some force (it may be tight if it's the first time prying), and the cover should come off easily. At this point, you can see the battery. 4. Use a pointed object (such as one end of a paperclip) to pry out the battery. 5. Replace the battery, and after replacing it, securely reattach the cover.

How many times have I changed the battery for my Fit key? I've got to share the experience. Find a small flat-head screwdriver, gently insert it into the side gap of the key to pry open the plastic shell—don't use too much force or you might break it. Inside is a button battery, model CR1616 or CR2025, which you can buy for a few bucks on Taobao or at a grocery store. When removing the old battery, remember the positive and negative orientation—usually the + sign faces up. Align the new battery properly when inserting it, then press the shell firmly to reset the slots. Test the unlock button immediately after finishing to make sure it works. Keep spare batteries handy to avoid last-minute hassles. A dead key affects keyless entry, so timely replacement ensures safety and convenience. The whole process takes just five minutes, saving you hundreds in labor costs at a repair shop. Remember to check the user manual to confirm the model to avoid mistakes.

I enjoy DIY tasks like this, where tools are key. You can pry open the Fit key fob shell with a coin or thin plastic card to avoid scratching the plastic. Once the shell is open, the battery inside is easy to remove—it's a CR1616. Use tweezers to remove the old battery for stability, and avoid touching the positive and negative terminals directly with your hands to prevent electric shock. When installing the new battery, ensure the electrodes match. Before reassembling, check if the light turns on. Always keep spare batteries on hand to prevent remote failure, especially since rainy weather can affect the signal. Buying batteries online is cost-effective—a pack for just over ten yuan can last years. After replacement, test all functions, including the keyless start. It's simple and efficient, saving you the hassle of waiting in line at the dealership. DIY is truly satisfying, especially when you master the tricks and get it done in a flash.

I replaced the Fit key battery, safety is key. When gently prying open the casing, avoid using excessive force to prevent plastic cracks or circuit damage. The most common battery model is CR1616—always verify the voltage matches when buying new ones. Wear anti-static gloves or use a cloth when installing the battery to avoid short circuits. Test the remote range immediately after installation. If the key doesn’t work, check the battery orientation or whether the casing is properly reset. For prevention, check the battery’s remaining power annually and replace it in advance. DIY saves money, but don’t force it—if unsure, spend a little to have it handled safely by a professional shop.
